Power Considerations
Each CTX670 Base and Expansion Cabinet houses a power supply that furnishes power to all of the
stations and some of the peripherals that interface with the cabinet (see
Table 1-23, “Strata CTX670
Electrical Characteristics” on Page 1-31 ).
Reserve Power
Two or four customer-supplied 12VDC reserve batteries can be connected to the system to maintain
normal operation during a power failure (see
Table 1-26 on Page 1-33 and Table 1-23 on Page 1-31 ).
The batteries are kept in a highly-charged state by the standard power supply and must be connected
when the system is operating normally. Fully charged batteries must be connected when normal AC
power is available, batteries cannot be connected after/during an actual power failure.
